Its great to have analysis like this and I'd like to see much more in future regarding BitShares' economics.
I'd suggest some changes in treatment, although its arguable what the optimal treatment is for some of these things.
BTC holders do not receive any transaction fees as revenue as they all go to miners. The dilution is an expense though, resulting in net loss and negative P/E. For BitShares, I personally would treat the fees as revenue, and the delegate pay (dilution) as expenses. So again EPS and P/E is negative.
I'm not sure BTC and BTS are strictly comparable though. BTC is positioning itself as free-market money, so there are other transactional metrics of value to owners, such as those shown here...

BTS is positioning itself as a profit-making enterprise, so there are other financial metrics of value to its owners, such as revenue growth, exchange transaction growth, active user growth, and once we have 2.0, compositional metrics such as UIA growth and establishment fees, and referral fee splits.
